Say I have entity A that is the parent with @OneToMany
association to entity B. Also say I set fetch mode to eager. So when I use a JPQL to fetch my entities A base on some filter do I need to use join in order to get its children?
You have to use join
when children are part of the query, for example:
select p
from parent p
inner join p.children c
where c ...
but you don't have to use fetch
before join to initialize entities.
